Description: 1. Polygon data created with data from ENC DIRECT TO GIS (http://www.nauticalcharts.noaa.gov/csdl/ctp/encdirect_new.htm)Large Scale (Band 4/5) ENC boundaries - includes all area in M_COVR except the LNDARE coverage(NaturalFeaturesA/Land_Area) was erased from coverage area (MetadataA/Coverage_Area) at both the “Approach” and “Harbor”scales then joining both resultant polygons. The scale of the compilation ranged from 1:150000 (smallest scale of Band 4 ENC used) to 1:5000 (largest scale of Band 5 ENC used)2. Location of navigation channels, port infrastructure, precautionary, pilot, and depth areas and contour lines are from large scale RNC.kap files, NOAA_RNC MapService, and ENC Direct to GIS.Delineation boundaries include port infrastructure with an inland buffer of 500 meters for ports that have less than 10,000,000 tons of total mass cargo transported through the port per year and an inland buffer of 1000 meters for ports with greater than 10,000,000 tons of total mass cargo transported through the port per year.Islands greater than 10 square miles remain as polygon parts within the port polygon 3. AIS data points found in http://www.marinecadastre.gov/ (which passage has the highest traffic for the most vessels) from May 2010 in UTM zone 11 and May 2009 and May 2010 in UTM zone 10.4.
